BACKGROUND Technical Field

The present disclosure relates to lighting systems for vehicle windows having plastic glazing.

Technical Background

Vehicles such as sedans, coupes, sports utility vehicles, vans, hatchbacks, and the like typically include one or more of front, side, quarter and rear window structures. Moreover, such vehicles include one or more light assemblies (e.g., a brake light, a puddle light). These parts and other parts may add to the cost and complexity of assembling a vehicle.

In this regard, light assemblies in vehicles include a large number of separate components. For example, a typical vehicle may have several different types of lights, including, for example, parking lights, turn indicator lights, brake lights, and the like. Each of these lights may be made from many parts. These parts add to the cost and complexity of assembling a vehicle. Accordingly, as recognized in U.S. Pat. No. 7,048,423 (“the '423 Patent”), it desirable to have a lighting assembly with fewer parts. The '423 Patent discloses an integrated light assembly including a plurality of lamps 210, 216 enclosed in a housing 202, which may serve as a lens for the lamps, and mounted on a substrate 204. Such portions of a light assembly may add to the overall weight of a vehicle, and the overall complexity and cost of manufacturing and assembling a vehicle. The above-noted problems with conventional light assemblies are compounded by recent trends to increase the number of lights provided on vehicles. For example, lights provided for aesthetic purposes and utility purposes.

The present disclosure aims to solve these problems and other problems in the prior art.

Additionally, any aspect of the disclosure utilizing the light unit 214 may be configured to provide illumination of an ornamental graphic, logo or the like. This graphic or logo may be in-molded in the portion 110, in the glazing 108, or both, or it may be a separate entity.

According to certain aspects of the disclosure, the window assembles disclosed herein may also include additional layers on top of the thermoplastic polymer layers. For example, a layer for increasing scratch resistance may be added to an exterior surface of the plastic glazing. As another example, an additional layer for adding more support to the thermoplastic polymer layers may also be added to an interior surface of the plastic glazing. This additional layer may be formed of a plastic, a metal, or other material for increasing the structural strength of the window.

As described above the plastic glazing the 100 may be manufactured using a molding process. In a particular aspect, a multi-shot injection technique may be used to form the plastic glazing 100. In a first shot, a clear translucent material may be injected into a mold cavity having a first volume to form the clear transparent portion 108. After the clear transparent portion 108 is formed, the mold cavity may be adjusted to a second volume and so on and so forth for receiving additional shots of material. In a second shot (or a third shot), a black or other colored opaque material for the portion 110 may be injected to the mold cavity such that it binds with the clear translucent material. The two materials may bind together through melt bonding. That is, heat from the injected opaque material may melt a surface of the already set clear translucent material such that a bond is formed between the two materials when they cool. During any one of the multi-shot injection molding processes the molded components 502, the cavity 212, the colored portion 102, or any other aspect set forth in the disclosure may be formed thus reducing costs and complexity of the manufacturing process. During any one of the multi-shot injection molding processes the light unit 214 or any other aspect set forth in the disclosure may be inserted and molded-in thus reducing costs and complexity of the manufacturing process.

Implementations of the light feature 50 manufactured consistent with the disclosure were found to provide greater than 10%-15% weight reduction in comparison to non-integrated implementations.
